Their rise is due to two factors: biotechnology, which has made it possible to synthesise them with precision, and the growing interest in treatments that stimulate the body's natural mechanisms rather than replacing them.<\/strong>. In cosmetics and longevity, peptides fit perfectly into this philosophy.<\/p>\n\n\n\n In the field of cosmetic<\/strong>peptides are incorporated into creams, serums or ampoules because of their ability to stimulate collagen and elastin production, improve skin texture and promote skin repair. Although they are not a \"topical botox\", they can help to improve firmness and radiance if the formulation is appropriate and the product is well preserved.<\/p>\n\n\n\n At medicine<\/strong>peptides are approved as drugs for the treatment of metabolic, hormonal or autoimmune diseases. These compounds are administered under medical prescription and control, as their action is potent and specific.<\/p>\n\n\n\n There is also a proliferation of research peptides<\/strong>available on the internet under the label \"for research use only\". They are not authorised for human use and may pose a serious health risk due to their lack of control, purity and traceability.<\/p>\n\n\n\n The peptides can be applied via topical<\/strong>, oral<\/strong> o injectable<\/strong>although each form has its own particularities.<\/p>\n\n\n\n Proteins are long chains of amino acids; peptides are shorter and act as bioactive fragments with specific functions. Compared to other cosmetic actives such as retinoids or vitamin C, peptides stand out for their role as \"messengers\" that tell cells what to do.<\/p>\n\n\n\n However, it is important to distinguish cosmetic peptides - safe and regulated - from those that mimic hormones or growth factors, used in medical or sports settings. Some of the latter are included in the World Anti-Doping Agency (WADA) prohibited substances list<\/strong>.<\/p>\n\n\n\n Before buying or recommending a product, it is useful to review some key points:<\/p>\n\n\n\n Be wary of any product without traceability or labelling indicating \"for research only\" or \"not for human use\".<\/p>\n\n\n\n In Spain, the peptide cosmetics<\/strong> can be freely sold if they comply with the European Cosmetics Regulation and are notified in the CPNP Portal<\/strong> of the European Union. The peptide drugs<\/strong>However, they can only be manufactured and dispensed with authorisation from the AEMPS, and in many cases require a prescription.<\/p>\n\n\n\n The pharmacies<\/strong> can also develop magistral formulations<\/strong> with peptides, provided that there is a prescription and that traceability and quality control standards are met.<\/p>\n\n\n\n The use and marketing of unauthorised injectable peptides - very common on foreign sites - is illegal in Spain and can lead to penalties for both the seller and the user.<\/p>\n\n\n\n The main risk of peptides outside of the health care circuit is the counterfeiting or contamination<\/strong>. Some products contain impurities, incorrect dosages or substances other than those declared. In addition, uncontrolled injectable use can cause serious adverse reactions.<\/p>\n\n\n\n Experts therefore recommend purchasing only regulated products, requiring the appropriate documentation and, in the case of injectable or therapeutic treatments, always using accredited medical professionals.<\/p>\n\n\n\n Peptides represent one of the most exciting frontiers of biotechnology applied to wellness and longevity. But their potential is only realised when used with knowledge, safety and responsibility. <\/p>\n\n\n\n En los \u00faltimos meses, los p\u00e9ptidos se han convertido en la nueva palabra de moda en el mundo del bienestar, la belleza y el rendimiento f\u00edsico.
